APPARATUS FOR THE PRODUCTION AND I NHALATION F OONE.

SPECIFICATION forming part of Letters Patent No. 499,572, dated 1116 I3, 1893. Application filed December 10, 1891. Serial No. 114,699. (No model.) Patented in Belgium September 21, 1 ;No. 96.4 1 and T0\a,ZZ whom it may concern:

Be it known that I, MARIE PAUL OUDIN, a citizen of the French Republic, residing at Paris, France, have invented a new and useful Improvement in Apparatus for the Production and Inhalation of Ozone, (for which Jules Ehlis has obtained a patent in Great Britain, N 0. 16,806, dated October 3, 1891, and in Belgium, No. 96,482, dated September 21, 1891,) of which the following is a specification.

This invention relates to improvements in apparatus for the production and inhalation of ozone and it consists particularly in the use of a glass tube hermetically closed, inclosing air or a gas at a'pressure, other than atmospheric pressure, which tube is connected with one of the poles of a source of electricity the other pole of which is connected to insulated metal plates placed in close vicinity of the said glass tube.

In the accompanying drawings, Figure l is a transverse vertical section; Fig. 2 a longitudinal section through an apparatus embodying my invention.

A is a wooden box or case supported on four legs, being entirely open at the bottom. The top or cover is provided with a hole to which a flanged and screw-tapped sleeve or neck 0 is fitted into which the lower end of the inhalation tube E may be screwed.

The side walls of the apparatus are provided with oppositeopenings into which is fitted a glass tube T, hermetically sealed at its ends and from which a portion of the contained air has been exhausted to form apartial vacuum therein. Or said tube may be filled with hydrogen gas or other light fluid forming a good. conductor of electricity. In

one end of tube '1 is inserted a metallic binding post B, sealed therein by fusion of the glass, the inner surface of said binding post being'in contact with the gas contained in said tube. Thus itwill be seen that the tube itself or rather its contained gas, acts as one of the electrodes, being in contact with the binding post B which forms one of the terminals of the secondary coil of an induction coil or other source of electric energy. On each side of this tube and at a short distance from it in England October 3, 1891 No. 16,806.

are arranged one or two metal plates M M,

which slightly spread apart at their base, in order to facilitate the passage of the current of air drawn in by aspiration through the pipe E. The metallic plates M, M are supported and held in place by insulators N. They communicate by a wire with the binding post 0, which is connected to the negative pole of the source of electricity. When an electric current is made to pass through this apparatus, a uniform dim light is produced between the tube T and the metal plates M M as a result of the discharge of the electric current. Thereby the ambient air is ozonized Without any formation of nitrous vapors as is the case in other glass tubes, where violet sparks are formed, and where no uniform and silent flow ofelectricity is obtained. In consequence of the draft produced by the tube E the ozonized air rises in the apparatus as indicated by the arrows, and escapes through the upper orifice of the tube E. The glass tube T may also be arranged in the apparatus in an inclined or vertical position and instead of the plates M M. being parallel with this tube this latter may be surrounded more or less.

completely but at a certain distance, by a sheet of metal.

Having thus described my invention, what I desire to secure by Letters Patent is 1. In an ozonizing apparatus, a glass tube hermetically sealed and filled with air or gas at a pressure less than the atmospheric, said tube being provided with a bind-ing post which has part of its metallic surface in contact with and exposed to the gas contained in the tube, and an electric circuit of which said binding post and tube form one'tcrminal, the other terminal of saidcircuit being in the form of a metal plate arranged adjacent to said glass tube, substantially as set forth.

2. The combination with a casing having a mouth piece and openings in its ends and bottom, of a glass tube mounted in the openings in the ends of said casing, said tube being filled with air or gas at less than the atmospheric pressure, and, being provided with a binding post having part of its metallic surface in contact with the gas contained in said tube, metal plates mounted vertically in said casing on opposite sides of said tube but at a slight distance therefrom and an electric circuit inclndinga generator, of which said binding post and glass tube form one terminal and the metallic plates in the casing form the other terminal, substantially as set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
